INTERLOCKING TILE.

To all whom it nm-y ommern:

Be it known that I, VANCE E. TAYLOR, a citizen of the United States of America, a resident of the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Interlocking Tiles, of which the following is a full, clear, and exact description, reference being bad to the accompanying drawings, forming a part of this specification.

My invention relates to tiles intended more particularly for use in building sewers and other conduits, and has for its object the production of a single ring tile sewer structure built up of segmental tile sections in such manner as to provide leak-proof end joints between the tile sections, this object being attained partially through the medium of tongue/and groove sealed connections between the ends of the tile sections, and partially through the provision of cavities in the tile sections into which mortar may become embedded. to form seals, aside from that formed between the tongue and groove portions otthe sections.

Fig. I is a perspective of a fragment of one of my tile sections showing the tongue at an end thereof.

Fig. II is a fragment of one of the tile sections showing a groove in its end suitable for the reception of the tongue shown in Fig. I.

Fig. III is a longitudinal section of portions of two oi the tile sections joined to each other.

In the accompanying drawings, A. and B designate tile sections adapted to be placed in interlocking relation with each other at their ends The tile section A. is provided with an end tongue 1, and the tile section B is provided with an end groove 3 adapted to receive the tongue of the section A. The opposite end of each section is similar to the end of the other section shown in the drawings.

When the blocks A and B are fitted together end to end, the tongue 1 of one section occupies a position between the two webs 5 and 6 adjoining thegroove 3 in the next tile section, as seen in Fig. III. The tongue 1 is carried by a Web 7 spaced from webs 8 and 9, thereby providing cavities 10 and 11 extending into the section at its end from which the tongue projects. Beyond the Specification of Lcttcrslatent.

inner end of the groove 3 in companion section is a web 12 spaced from the webs 5 and (5, thereby providing cavities 13 and 14 at opposite sides of the web 12.

When mortar is applied to the ends of the tile sections A and B, said ends and the tongue 1 are coated with mortar and the mortar enters into the groove 3 in the section B and also enters into the cavities 10 and 11 in the section A. Then when the sections are brought together end to end, and the tongue of one section is forced into the end groove in the other section, mortar lying in the groove will. be partially forced theretrom into the cavities 13 and i l, at opposite sides of the web 12 extending to the base of said groove. A mortar seal joint is therefore i iilrnished between the opposing ends of the tile sections at opposite sides of the tongue 1 and at the end of said tongue, the mortar seal extending also into the cavities 10 and 11 in the section A, back of the end of said section and into the cavities 13 and 14 beyond. the base of the groove and at opposite sides of the web 12. Such a mortar joint forms an etl'ective seal at the junction oi the tile sections to preclude the passage of mortar theretlnough, and the mortar is securely held in the joint. However, as an adcv .ional sealing provision, I preferably form in the tile sections cavities 15 and 16, which extend inwardly from their ends and coincide with each other when the sections are joined end, to end. These cavities 15 and 1.6 also receive mortar when it is applied to the ends of the tile sections, so that they serve as supplennrntal bailiies tor the exclusion oi moisture that might. pass directly along the end faces of the tile sections in the absence of the sealing mortar extending into said cavities.

To eliminate the possibility of mortar being scraped from the surfaces of the tongue 1 and the walls of? the end groove 3,, when tile sections are fitted together, I form ribs 2 upon the faces of the tongue 1 and ribs 4 upon the walls of the groove 3, which, by coinciding with each other, serve to pre vent the tongue from scraping against the walls of the groove when introduced into the groove. As a consequence the tongue will always be so positioned in the groove of: the adjoining block as to provide a body of mortar at both sides of the tongue, even in the event of the tile sections being imperfectly fitted to each other.

I claim:

An interlocking tile structure comprising tile sections, one of which is provided with an end groove and the other With an end tongue entering into said end groove, each of said tile sections being provided with a plurality of cavities which extend longitudinally through said tile sections, the cavi-Q ties of one tile section being adapted to register with the cavities of another tile section when said tile sections are plaeedin juXta- VANCE E.
